      Drug Name Diclofenamide Digitoxin
      Mechanism 1 Hypokalemia Hypokalemia
      Key Mechanism Factor 1
Factor Name Hypokalemia
Factor Description Hypokalemia is a condition in which the amount of potassium in your blood is lower than normal. If you are mildly hypokalemic, you may not have any signs or symptoms, but severe hypokalemia may have the following symptoms: fatigue, constipation, frequent or heavy urination, muscle cramps or skin tingling, muscle weakness, and a fast or irregular heartbeat.
      Mechanism Description
  • Increased risk of hypokalemia by the combination of Diclofenamide and Digitoxin

      Drug Name Diclofenamide Digitoxin
      Mechanism 2 Hypomagnesemia Hypomagnesemia
      Key Mechanism Factor 2
Factor Name Hypomagnesemia
Factor Description Hypomagnesemia is a condition that occurs when you have too much magnesium in your body. Symptoms of hypomagnesemia include: nausea, vomiting, neurological damage, abnormally low blood pressure (hypotension), flushing, and headaches.
      Mechanism Description
  • Increased risk of hypomagnesemia by the combination of Diclofenamide and Digitoxin 

Recommended Action
      Management Digoxin, potassium and magnesium levels should be followed closely. Hypokalemia and hypomagnesemia should be treated appropriately. Digitalis dose adjustments may be required. Patients should be advised to notify their physicians if they experience signs of possible digoxin toxicity or electrolyte disturbances, such as weakness, lethargy, muscle pains or cramps, nausea, anorexia, visual disturbances, or irregular heartbeats.
